§ The work

I add AI features to an existing app or build them from scratch: chat over your documents, smart automation, classification, drafting. The focus is on something reliable and useful, not a demo that breaks on the second prompt.

What is included

  • RAG (chat over your own docs or data) with sensible retrieval
  • Streaming responses and proper error and rate-limit handling
  • Prompt and model setup tuned for cost and quality
  • Guardrails so it fails gracefully instead of hallucinating freely

What you get

  • The AI feature integrated into your app and deployed
  • Documented code in your repo
  • Notes on cost per request and how to tune it

Scoped per feature after a short call.

§ Questions

Which model should I use?

I will recommend based on your task and budget. Often a cheaper model is enough; I will tell you when it is not.

Will this get expensive?

I design for cost from the start (caching, the right model per task) and hand you the per-request numbers so there are no surprises.

Can it use my private data?

Yes, that is the common case. Your data stays in your infrastructure and is retrieved at query time.
